A major breakthrough in synchronisation research was achieved by Pecora and Carroll [1]}, whose seminal work defined the Master Stability Function (MSF): a functional analysis of the synchronisation manifold's stability for generic graphs of diffusively-coupled, identical, (time-continuous or discrete) dynamical systems. The MSF allows to decouple the dynamical properties of the dynamical units composing the coupled system with its topological properties (similar to the work by Fujisaka and Yamada [2]}). In spite of the MSF breakthrough, and because of the broad range of dynamics and graphs that can be analysed, there are still plenty of open-questions that can aid in the design of stable synchronous systems and continue increasing our understanding of this fascinating collective phenomenon.
